Thats not good man. You shouldn't exercise hours before your sleep. The reason is, after your work out, your body is still going crazy pumping blood everywhere, which makes parts of your brain more alert resulting in a shittier sleep.

I adapted to my pattern already. I wake up after a 7-8 hour sleep feeling fine. A lot of people hit the gym after work, that's why high flow hours are from 6-10PM.
